# Shopify Hello World

## Overview

Minimal working example: query your store's products using the Shopify GraphQL Admin API. Uses `@shopify/shopify-api` with a custom app access token for zero-friction setup.

## Prerequisites

- Completed `shopify-install-auth` setup
- A Shopify development store
- An Admin API access token (`shpat_xxx`) from Settings > Apps > Develop apps

## Instructions

### Step 1: Create Project

```bash
mkdir shopify-hello-world && cd shopify-hello-world
npm init -y
npm install @shopify/shopify-api dotenv
```

### Step 2: Configure Environment

```bash
# .env
SHOPIFY_STORE=your-store.myshopify.com
SHOPIFY_ACCESS_TOKEN=shpat_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
SHOPIFY_API_KEY=your_api_key
SHOPIFY_API_SECRET=your_api_secret
```

### Step 3: Write the Hello World Script

Initialize the Shopify API client with `LATEST_API_VERSION` (imported from `@shopify/shopify-api`), create a custom app session, then query shop info and products via GraphQL.

See [Hello World Script](references/hello-world-script.md) for the complete implementation.

### Step 4: Run It

```bash
npx tsx hello-shopify.ts
# Or compile first:
npx tsc hello-shopify.ts && node hello-shopify.js
```

## Output

Expected console output:

```
Store: My Dev Store
Currency: USD

Products:
  - Classic T-Shirt (ACTIVE, 150 in stock)
      Variant: Small — $29.99 (SKU: TSH-SM)
      Variant: Medium — $29.99 (SKU: TSH-MD)
      Variant: Large — $29.99 (SKU: TSH-LG)
  - Coffee Mug (ACTIVE, 42 in stock)
      Variant: Default Title — $14.99 (SKU: MUG-01)

Success! Your Shopify connection is working.
```

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `HttpResponseError: 401 Unauthorized` | Invalid or revoked access token | Regenerate token in Shopify admin > Settings > Apps |
| `HttpResponseError: 403 Forbidden` | Token lacks required scopes | Enable `read_products` scope in app config |
| `HttpResponseError: 404 Not Found` | Wrong store domain or API version | Verify store URL is `*.myshopify.com` |
| `ENOTFOUND your-store.myshopify.com` | Store domain typo or DNS issue | Double-check `SHOPIFY_STORE` value |
| `GraphqlQueryError` with `userErrors` | Invalid query syntax | Check field names against API version docs |
| `MODULE_NOT_FOUND @shopify/shopify-api` | Package not installed | Run `npm install @shopify/shopify-api` |

## Examples
